"Enterprise Web sites typically have relatively tight control over their own software development lifecycle (SDLC) and security practices," the report says. "However, they very often rely on third-party partners to provide content, advertisements, or software applications that power the enterprise’s Web sites."
These partners often lack enterprise-level controls, Dasient's report observes, which makes their systems and software are more susceptible to attack and infection.
Such content presents higher risk than is necessary.
The problem, Dasient argues, is that these vulnerabilities are often structural, and are thus not easily remedied. A news Web site, for example, can't simply decide to forego advertising because some ads carry malware.
Certainly, Web page infections are a problem. A new Web page gets infected every 1.3 seconds, according to Dasient, which says that the number of malware-infected Web pages has grown by a factor of 12 in four years.
Related research from Websense last year indicates that 77% of Web sites with malicious code are legitimate sites that have been compromised.
Dasient's answer is its Malware Monitoring system. But more than products or services, companies need to demand security from their partners, if they want to protect their reputation and their brand.
